Mechanics (Greek μηχανική) is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. It can also be defined as a branch of science which deals with the motion of and forces on objects.

Hi
Newton's second law is a real law of motion as it implies first and third law. From newton's second law; F=ma If F=0 a=0 Thus, says when net external force is 0,acceleration is 0. From second law; P+Pï=Fî+Fï (P is momentum of first object and Pï that of second object. Respectively is Fî and Fï ;final momenta) Then, P-Fî=Fï-Pï P-Fî=-(Pï-Fï) Ft=-(Fįt) F=-Fį where t is time interval, F is force on first object by second and Fį vice-versa . Thus, newton's third law is implied by second. Hence, second law alone is sufficient to rule the motion and is called real law of motion.

Hey

Reyansh Singh 6 years ago

The centripetal ('center-seeking') acceleration is the motion inwards towards the center of a circle. Formula: The centripetal acceleration is equal to the square of the velocity, divided by the radius of the circular path. ac = v2/r Where, ac = acceleration, centripetal, m/s2 v = velocity, m/s r = radius, m ☺️

Spermatogenesis is a concerted sequence of events during maturation of spermatogonia into spermatozoa. The process involves differential gene-expression and cell-cell interplay regulated by the key endocrine stimuli, i.e., follicle-stimulating hormone (FSH) and luteinizing hormone (LH)-stimulated testosterone. In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production. In men, follicle-stimulating hormone acts on the Sertoli cells of the testes to stimulate sperm production (spermatogenesis).
